Abstract
In the previous paper, hydrolysis of α-alkyl and α, α-dialkyl N-acetylsarcosinonitriles and N-acetylglycinonitriles with alkali or acid was reported.
In both series it was found that under alkaline conditions α, α-dialkyl compounds mainly changed to intramolecular cyclization compounds (imidazalones) and in the case of glycino series there was an equilibrium between amide and imidazolone.
The imidazolones were also obtained under acidic conditions in both series, and in sarcosino series, the corresponding imidazoline-4-imide was formed in addition to the imidazolone.
